1. Math Mammoth news

"I just wanted to thank you for this excellent curriculum! I tried 3 different 1st grade curriculums for my daughter and none of them were working well for her. Math was just not clicking. I got the entire curriculum (to use for both her, my younger daughter and my numerous tutoring students). She started 1st grade on February 3rd and she will complete the entire 1st grade course (workbooks A & B) by April 25th! (An entire grade in under 12 weeks!) She finally understands the concepts, and now math is her favorite subject! The students I tutor are also benefiting from the curriculum and love how everything is explained.

Math was never my favorite subject in school, and (like my daughter) I now LOVE it and am seeing math in an entirely new light! Thank you!"

5. New cryptographic algorithms

From the news...

Investigators have created new cryptographic algorithms that are based on particularly hard mathematical problems. They say they would be virtually unbreakable!

Cryptographic methods are typically created following the ad-hoc principle: somebody comes up with an algorithm; others attempt to break it — if they don't succeed, it means that the algorithm is secure. The team headed by Prof Dr Eike Kiltz who holds the Chair for Cryptography at the Ruhr-Universität Bochum opted for a different approach. They base their security algorithms on hard mathematical problems. Read more:
